Ever tried to pin down a date for the start of "religion"? It's a nightmare. Honestly, asking what is the oldest religion in the world is a bit like asking which drop of water started the rainstorm. Depending on who you ask—an archaeologist, a theologian, or a tribal elder—you’re going to get a wildly different answer. Some people point to the Rigveda. Others look at the cave paintings in Lascaux and see the birth of the divine.
It's messy.
History isn't a straight line. We want it to be. We want a neat little plaque that says "Religion Started Here, 3500 BCE." But the reality is a blur of oral traditions, buried artifacts, and prayers whispered long before humans knew how to write. If we’re talking about "organized" religion—the kind with books, priests, and specific rules—most scholars are going to point toward the Indus Valley. But if we’re talking about the impulse to worship something bigger than ourselves? Well, that goes back to the dawn of the species.
The Heavyweight Champion: Hinduism
When most people google "what is the oldest religion in the world," they are looking for Hinduism. And for good reason. It’s often called the Sanatana Dharma, which basically translates to the "Eternal Way." Unlike Christianity or Islam, Hinduism doesn't have a single founder. No "Year Zero."
It evolved.
The roots of Hinduism stretch back over 4,000 years into the Indus Valley Civilization. We’re talking about a time when the city of Mohenjo-daro was a bustling metropolis with advanced drainage systems while much of the world was still living in basic huts. The Vedas, the oldest sacred texts of Hinduism, were composed roughly between 1500 and 1200 BCE. But here's the kicker: they were passed down orally for centuries before anyone even picked up a stylus to record them.
Think about the sheer brainpower required for that. You had generations of priests memorizing thousands of verses with perfect inflection. If you mess up a syllable, the ritual is ruined. That’s dedication.
The complexity of Hinduism is what makes it so enduring. It isn't just one thing. It's a massive, sprawling umbrella that covers everything from the monism of the Upanishads to the vivid, colorful devotion of the Puranas. It has survived the rise and fall of empires, the British Raj, and the digital age. It's still here. That longevity is why it usually wins the "oldest" title in most textbooks.

If we define "religion" as a written tradition, then Hinduism is the clear frontrunner. But what about the stuff that came before writing? Before we had the Sanskrit of the Vedas, we had the Oldest Known Temple at Göbekli Tepe in modern-day Turkey.
This place is a mind-bender.
Dated to around 9000 BCE, Göbekli Tepe predates Stonehenge by over 6,000 years. It predates agriculture. Think about that for a second. We used to think that humans settled down, started farming, and then built temples. Göbekli Tepe suggests the opposite. It suggests that the urge to worship, to gather around massive T-shaped stone pillars carved with images of lions and scorpions, is what actually drove us to settle down in the first place.
Was it a "religion"? Probably. But since they didn't leave a handbook, we can only guess what they were praying for. Likely rain, protection, or a good hunt. The basics.
The Spirits in the Trees: Animism
If you want to get really technical about what is the oldest religion in the world, you have to talk about Animism.
Animism isn't a single church. It's a worldview. It’s the belief that everything—rocks, rivers, thunder, animals—has a soul or a spirit. It's the "original" human religion. Tens of thousands of years ago, our ancestors didn't see themselves as separate from nature. They were part of a conversation with it.
- The Australian Aboriginal Dreamtime (Alcheringa) is arguably the oldest continuous religious perspective on Earth.
- It dates back at least 65,000 years.
- It involves a complex understanding of the land, ancestral beings, and the law.
When you look at the 40,000-year-old cave art in Indonesia or France, you aren't just looking at pretty pictures of bison. You're looking at a ritual. Anthropologists like Jean Clottes have argued that these caves were sacred spaces, likely used for shamanic journeys. To these ancient people, the wall of the cave was a veil between this world and the spirit world.
Is Animism a religion? By modern standards, it’s often dismissed as "superstition" or "folk belief." But that’s a narrow way of looking at it. It provided a moral framework and a sense of meaning for humans for a much longer period than any modern faith has existed.

Zoroastrianism: The Bridge to the Modern World
We can't talk about ancient faiths without mentioning Zoroastrianism. Founded by the prophet Zoroaster (or Zarathustra) in ancient Persia, this religion is often overlooked, but its DNA is everywhere.
It’s old.
While dates are debated, many scholars place Zoroaster around 1200–1000 BCE, making it roughly contemporary with the early Vedic period. It was the first major religion to introduce the idea of a single, all-powerful God (Ahura Mazda) fighting against an embodiment of evil (Angra Mainyu).
Sound familiar?
If you grew up in a household that talked about heaven, hell, judgment day, and angels, you are essentially living in the shadow of Zoroastrianism. When the Jews were in exile in Babylon, they came into contact with Persian ideas. Those ideas—specifically the dualism of good versus evil—leaked into Judaism, and later into Christianity and Islam.
Zoroastrianism is still practiced today, mainly by the Parsi community in India, though their numbers are small. It’s a "living" fossil of a faith that changed the course of human thought. It moved us away from the cyclical time of the ancients and into the linear time of the modern West.
The Bronze Age Contenders: Judaism and Others
Judaism is often the "oldest" religion people think of in a Western context. Its origins are firmly planted in the Bronze Age. The story of Abraham is traditionally dated to around 1900 BCE, though the actual writing of the Torah happened much later, likely during the Babylonian exile in the 6th century BCE.
What makes Judaism unique among its peers was its shift toward Ethical Monotheism.

Most ancient religions were about keeping the gods happy so they wouldn't kill you with a drought. Judaism introduced the idea that God cared about how you treated your neighbor. It was a revolutionary shift.
But compared to the Vedic traditions of India, Judaism is a bit of a newcomer. And if we look toward China, we have Taoism and Confucianism emerging around 500–600 BCE. These are "young" in the grand scheme of things, but they've had a massive impact on the spiritual life of billions.
Why the Answer Changes Depending on Your Definition
So, what is the oldest religion in the world? Let's break it down by category, because a single answer is basically impossible.
The Continuous Living Tradition: Hinduism.
If you are looking for a religion that was practiced 3,000 years ago and is still practiced in a recognizable form today, Hinduism wins. The mantras chanted in a temple in Varanasi today aren't that different from the ones chanted three millennia ago.
The Oldest Organized Structure: Sumerian/Egyptian Polytheism.
If we're talking about temples, hierarchies, and written records, the Sumerians and Egyptians were the first out of the gate around 3000 BCE. They had complex pantheons, but these religions are "dead." No one is seriously worshipping Enlil or Ra anymore (outside of small neo-pagan circles).
The Oldest Spiritual Impulse: Animism/Shamanism.
If you define religion as "humanity seeking the divine," then it goes back to the first time a Homo sapiens buried their dead with flowers or beads. That’s at least 100,000 years ago.
Why Does This Matter?
Understanding the age of these faiths isn't just a trivia game. It shows us that humans have always been searching for the same thing. Whether it’s a Vedic priest in 1500 BCE or a tech worker in 2026, we’re all trying to figure out why we’re here and what happens after we leave.
Religion was our first science. It was our first attempt to explain why the sun rises and why the seasons change. It was our first law code. When you look at the "oldest" religion, you're really looking at the "oldest" version of ourselves.
Actionable Insights for the Curious
If you want to dive deeper into the ancient world, don't just read a Wikipedia summary. You've got to look at the primary sources and the physical evidence.
- Read the Rigveda: You don't have to read the whole thing, but look at the "Nasadiya Sukta" (the Hymn of Creation). It’s incredibly humble. It basically says, "Maybe even the gods don't know how this all started."
- Visit (Virtually) Göbekli Tepe: Look at the 3D scans of the site. It challenges everything we were taught in school about the timeline of civilization.
- Explore the "Gathas": These are the oldest parts of the Zoroastrian Avesta. They are the actual words of Zoroaster and give you a window into a world of fire-worship and moral struggle.
- Study Indigenous Oral Histories: Look into the work of Bruce Pascoe or other scholars who document the complexity of Aboriginal Australian spiritual systems. It’ll shatter any idea that "primitive" means "simple."
The "oldest" religion isn't a trophy to be claimed by one group. It's a massive, tangled tree with roots that go deeper than our records can follow. We are just the newest leaves on the branches.
